Embodiment Construction

[0043] The arrows in the figure are intended to show the flow of fuel vapor and liquid fuel in the system. Solid arrows indicate liquid fuel, while dashed arrows indicate fuel vapor. Dotted arrows indicate vapors that are vented to the atmosphere after hydrocarbons or other polluting gases have been removed from them.

[0044] figure 1 A system 1 for treating fuel vapors 5 in a fuel tank 2 of a vehicle is schematically shown according to a first exemplary embodiment, the system 1 comprising the fuel tank 2 and a fuel vapor cooling device 3 connected to the fuel tank 2 . Fuel 4 and fuel vapor 5 are present in fuel tank 2 . The fuel vapor cooling device 3 is shown in the figure as a conventional cooler. This should be considered as an example only, without limiting the implementation of the fuel vapor cooling device 3 .

[0045] The fuel vapor cooling device 3 is arranged to receive fuel vapor 5 evaporated from the fuel 4 in the fuel tank 2 . In the fuel vapor cooling devic...

Abstract

The disclosure relates to a system (1) comprising a fuel tank (2) and a fuel vapour cooling arrangement (3) connected to the fuel tank (2). The fuel vapour cooling arrangement (3) is arranged to receive fuel vapour (5) evaporated from the fuel (4) in the fuel tank (2). In the fuel vapour cooling arrangement (3), the evaporated fuel is condensed into liquid fuel. The fuel vapour cooling arrangement (3) is arranged outside of the fuel tank (2). A valve (7) is arranged between the fuel tank (2) and the fuel vapour cooling arrangement (3) to control the opening and closing of the connection between the fuel tank (2) and the fuel vapour cooling arrangement (3). The disclosure also relates to a method for handling fuel vapour (5) in a fuel tank (2) of a vehicle.

Description

technical field [0001] The present disclosure relates to a system and method for treating fuel vapors in a vehicle fuel tank. Background technique [0002] In a vehicle fuel tank, fuel vapors may be generated, for example, during refueling or when the fuel is heated due to the vehicle being placed in the sun. In order for the pressure inside the fuel tank to not exceed the design pressure, it is necessary to remove fuel vapors from the fuel tank. However, due to emissions regulations, fuel vapors cannot be vented directly into the atmosphere, which would cause pollution. [0003] Evaporative emission canisters (also known as carbon canisters or charcoal canisters) are typically attached to a vehicle's fuel tank to absorb fuel vapors that would otherwise be vented into the atmosphere. Due to stricter emissions regulations around the world, evaporative emissions canisters continue to grow in size in order to increase their ability to absorb fuel vapors. The increasing size ...
